Abstract: A method of weather observations by a constellation comprises at least a first cluster of three micro-satellites each orbiting around earth, and each micro-satellites comprises a spectrometer. Orbiting the three micro-satellites of the first duster around the earth in three separate orbits offset with respect to one another. Staggering the three micro-satellites with respect to one another as they orbit. Selecting the offset and the staggering, of each of the three micro-satellites with respect to one another, so that each one of the three micro-satellites have a substantially identical viewing area as each one of the three micro-satellites orbits around the earth. Sequentially collecting observations, from each of the three micro-satellites, as the micro-satellites orbit around the earth and observe substantially identical viewing areas, to separately gather atmospheric measurements and provide critical data for weather forecasting by infrared temperature and humidity soundings and motion vector winds of the earth.

Abstract: A radiation measuring device for measuring electromagnetic radiation originating from an external source. The radiation measuring device includes, a spectrometer, a pyranometer, a pyrgeometer, a diffuser, and a control unit. The spectrometer and a pyranometer are positioned in a sensor zone of a housing of the radiation measuring device. The spectrometer measures visible shortwave radiation and near-infrared shortwave radiation received at the sensor zone. The pyranometer measures shortwave radiation received at the sensor zone. The pyrgeometer is positioned in another sensor zone of the housing and measures longwave radiation received at the other sensor zone. The control unit receives radiation measurements from the spectrometer, pyranometer, and pyrgeometer. A corrected amount of radiation received at the sensor zones of the radiation measuring device is determined from the received radiation measurements. Other embodiments are described and claimed.

Abstract: A multi-spectral imager useful for weather mapping, comprising an array of filters on at least one focal plane array (FPA) including pixels. Each of the filters are associated with a different set of the pixels, and each of the filters transmit a portion of electromagnetic radiation, comprising a different band of wavelengths, to the set of the pixels associated with the filter. A circuit connected to the pixels reads out a signal outputted from each of a plurality of different pixels in the set and outputs the signals to an adder. The adder sums the signals from each of the plurality of different pixels in the set to form a sum used for generating a weather map.

Abstract: A protective sheath having a closed end and an open end is sized to receive a hand held spectrometer. The spectrometer can be placed in the sheath to calibrate the spectrometer and to measure samples. In a calibration orientation, an optical head of the spectrometer can be oriented toward the closed end of the sheath where a calibration material is located. In a measurement orientation, the optical head of the spectrometer can be oriented toward the open end of the sheath in order to measure a sample. To change the orientation, the spectrometer can be removed from the sheath container and placed in the sheath container with the calibration orientation or the measurement orientation. Accessory container covers can be provided and placed on the open end of the sheath with samples placed therein in order to provide improved measurements.

Abstract: A cavity-enhanced absorption spectroscopy instrument has an optical cavity with two or more cavity mirrors, one mirror of which having a hole or other aperture for injecting a light beam, and the same or another mirror of which being partially transmissive to allow exit of light to a detector. A spherical-spherical configuration with at least one astigmatic mirror or a spherical-cylindrical configuration where the spherical mirror could also be astigmatic prevents a reentrant condition wherein the injected beam would prematurely exit the cavity through the aperture. This combination substantially increases the number of passes of the injected beam through a sample volume for sensitive detection of chemical species even in less than ideal conditions including low power laser or LED sources, poor mirror reflectivity or detector noise at the wavelengths of interest, or cavity alignment issues such as vibration or temperature and pressure changes.
